PINPOINT TEST O: DTCs C1222, C1233, C1234, C1235 AND C1236 - WHEEL SPEED SENSOR INPUT SIGNAL MISSING/MISMATCH

Normal Operation
The wheel speed sensor and sensor ring generate a signal to the anti-lock brake system (ABS) module that is proportional to wheel speed. The ABS module compares wheel speed inputs from all wheel speed sensors to determine an impending wheel lockup. Incorrect tire size can set these DTCs as well.

Possible Causes
^ Mismatched tire sizes
^ ABS module
^ Wheel speed sensor ring
^ Wheel speed sensor
